525. Autoregressive Mixers as Efficient Neural Quantum State for Ground State Search

Mr Faith Oyedemi (University of Ottawa, ON Canada)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

In recent years, Neural (network) Quantum States (NQS) emerged as powerful and reliable variational ansätze for studying strongly correlated quantum many-body systems. Since then, architectures such as restricted Boltzmann machines, recurrent neural networks, and convolutional neural networks, have been employed as wave function ansätze in variational Monte Carlo approaches to finding ground...

681. Disorder Resilient Entanglement in the Rare-Earth Dimer Magnet BiYbGeO₅

Gavin Hester (Brock University)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral (Non-Student) / Orale (non-étudiant(e))

In the search for exotic entangled states in quantum magnets, understanding how disorder affects the stability and properties of quantum ground states remains an open problem. Quantum dimer magnets, where neighboring spins form entangled singlet pairs, provide a particularly clean platform for addressing this question.
Our study centers on the rare-earth dimer magnet BiYbGeO₅, previously...

799. Effects of large strain gradient in ferroelectrics and multiferroics on their local polarization and magnetization field profiles, as well as on their magnetoelectric coupling

Vinayak Venkataraman (Institut National de la Recherche Scientifique)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Ferroelectrics and multiferroics have been widely recognized to play a significant role in next generation energy-efficient electronics, spintronics, and computing technologies, particularly in the fields of non-volatile information storage, sensing, actuation, and in-memory computing. Whilst ferroelectrics are well utilized today in piezoelectric actuators and sensors, RF/SAW filters,...

616. Exploring Alternative Layered Materials as Gate Dielectrics for 2D Material Based Devices

Isaac Lagaud (NRC / University of Ottawa)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The performance and scalability of two-dimensional (2D) materials based quantum electronics devices critically depends on the choice of gate dielectric. In gate-defined quantum devices, high-κ dielectrics enhance electrostatic control and reduce gate leakage. Hexagonal boron nitride (hBN), a 2D layered material, has become a widely used dielectric due to the clean interface it forms with 2D...

784. Machine Learning Approaches to Identify New Features in Infrared Images of Scored Cross-linked Polyethylene Pipe Subjected to Accelerated Aging

Zachery Evans (University of Guelph)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Cross-linked polyethylene (PEX) pipes are being used increasingly for water transport and heating applications. The pipes are exceptionally reliable but sometimes unexpected failures occur. We are using infrared microscopy, accelerated aging and machine learning analysis techniques to understand the mechanisms of pipe aging, degradation and failure [1-3]. In previous studies, we implemented...

973. Resonant X-ray Reflectometry of a Mn3Ge-based Quantum Heterostructure

Ms Meemansha Bahuguna (University of Saskatchewan)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Topological materials offer many interesting quantum phenomena such as anomalous Hall effect(AHE), topological Hall effect (THE), quantum spin liquid state, and skyrmion lattice. Among thesematerials, Mn3+xGe is one of the interesting materials as it has a triangular spin-lattice in the kagomenetwork. Due to this arrangement, collinear antiferromagnetic (AFM) alignment is impossible...

551. Studying Quantum Chaotic Behaviour in Disordered Materials via Quantum Computing

Christopher Kouton (University of Ottawa)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

In chaotic dynamics, the eigenstate thermalization hypothesis (ETH) posits that quantum systems evolve toward an equilibrium state over time, regardless of their initial state. Equivalently, the expectation value of an observable with few degrees of freedom will relax towards a thermal value despite the wavefunction evolving through time [1]. However, there exist quantum mechanical phenomena...

674. Visualization of Defect Electronic states in Layered Semiconductor CrSBr

Jonathan Brunette (University of Ottawa)

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Chromium sulfur bromide (CrSBr) is a 2D magnetic semiconducting material with a rectangular lattice that has attracted a lot of attention in recent years as it combines a rich magnetic phase diagram with axis-dependent electronic and optical properties. The presence of defects in CrSBr is believed to be connected to the details of the magnetic order and excitonic responses, yet their nature,...
